Be it known that LjALrnED CARLSON, a

`citizen of the yUnited States, residing at "Klamath Falls, in the 'county ofKlaInath yand State of Oregon,'have invented certain new and useful vImprovements in- Gearing, of which the following is ya specification.

The present inventiou'relates to improvelments in gearing by means of which driving power is transmitted` to drivenv parts to do work. T he general object may bey said to ,consistY in :the-provisionof a simple assemlblag'e ofparts in such'relation as to permit of maintenance of lubrication, requiring the minimum amount of replenishment and .eliminating likelihood of leakage.

Another object is to provide means of this yclass for convertingfrotary motion ofthe driving elementinto rotary motion of the driven element.

'y These and such otherobjects as may hereinafter appear are attained bythe novelcon-A struction, combination and arrangement of parts to behereinafter specifically described and claimed.v Reference will now be had t0 the accompanyingdrawings forming a part of this specification, wherein:

Figurey 1 is a jvertical sectional view y through an embodiment of thisinvention,

v Fig. 2 is a horizontal sectional view on the line 2-2 `of Fig. '1; and

(Fig. '3 isa fragmentary'sectional view taken kabouton the plane indicated bythe line'3-3 of Fig. 2. k35

Throughout the following detail descrip-` tion and on the several iiguresof lthe drawings, similar parts are referred to byvlike reference characters.; g j f.

The embodiment of theinvention herein described is depicted in` itsV adaptation Ito windmill constructionsbut'l.do'not desire to' be' restricted to krsuch type of embodiment inasmuch as the ymechanism capable Vof being utilized for other purposes. J

Referring to they drawing and specifically describing'the device, 1 indicates a casing which in this` instance constitutesan oiljreservoir, accover2 being provided forsaid casing and suitably fastened thereto by conventional means as indicated zit-3.` Extending into the casing from'one side is arranged y the drive shaft 4 which in this application ofthe device isthe 'shaft for the wind wheel (not illustrated).

site side of the casing 1 in a similar box 6. l

i Said shaft carries within the casing a bevel drive pinionV 7 keyed to said. shaft and arranged to'actuate the planetary gear unit now to be speciically described.

The unit just referred to consists of a frame formed by the lower plate 8 which, as

will be observed particularly in Figs. 2 and 3, is formed with suitable spaced lugs 9 on its upper surface to which the upper plate 10y of the frame is secured by the fastening {meansor screws 11. The plates are arranged 'vinspaced relation and held thus by the lugs ,9 above referred to, and journaled between said platesV are the outer pinions 12 12 meshing with an annular gear rack 13 formedon interior and lower portion of the casing 1. driven shaft 14 which in this mechanism would be the vertical pump rod, extends upwardly through the bottom of the casing 1 to a point substantially cen- ,y

trally thereonfrwhere it is lixed to the offset hub 15 of the centra-l gear 16 of the planetarywunityby means of the pin 17. The outer pinions l2 above referred to mesh with this gear 16 at opposite sidesy thereof.V At this point it may be especially noted that one .of the distinct features of this gearing are rangement isthe osetting of the hub 15 so that it extends to a point above the level vrofthe lubricant which is contained in the lcasing 1. It will be obvious that since the oil level is below the upper extremity of the shaft, said oil will not have a tendency to 4leak from Vthe casing, the leakage being precluded by utilizing a sleeve 18 surrounding the shaft 14 and having threaded connection at 19 with the casing. This vsleeve extends' upwardly to a point adjacent to the upperV portion of the4 hub 15 and the bore of the sleeve is preferably larger than the diameter'of the shaft, 14 so that no frictional contact will be made with said sleeve. p.

` Surrounding the sleeve and intermediate same and the gear 16 I preferably introduce a brass bushing 20 and the lubricant is dis'- tributed tothe friction surface of this bushing by drippings which flow from the inclined drive shaft 4 and pass through the oil passages 21 extending through the hub 15. Motion is obtainedv from the drive shaft 4 and its bevel gear 7 through the horizontal 4lubricant about the shaft and bevel gear 22 which is fiXedly secured to the upper surface of the upper plate l0 by the fastening means or screivs From the foregoing it wil be obvious that rotation of the shaft fl- Will actuate the bevel gear '7, in turn transmitting its motion to the gear 22 vvhich transmits its rotary motion to the planetary gear frame and by reason of the intermeshing relations of the outer pinions l2 with the casing rack 13 the frame revolves about the shaftld as an axis and the latter is rotated by the gear 16 incident to suoli rotation of the frame. Therefore, the rotary motion of the drive shaft d is taken ofi to do Work by revolution of the driven shaft il for actuating the pump nechanisin of the Windmill, not herein'illustrated.

rllhe boxes or journals of the drive shaft d are lubricated by the lubricant contained in the casing l which is carried up by the gear 7 from its contact With the gear 22 and passes douf'nivardljf' on the shaft in the manner hereinbefore indicated. 'lo insure that the box 6 is properly lubricated l provide the gear 'i' with projecting arm 24C which carries the allows it to drip upon the upper surface of the box 6 from whence it passes through the passage 25 to the bearing.

The construction above t escribed, it Will be apparent, constitutes a windmill head and the casing issuitably formed with ostanding apertured spaced supports 26 on which the vane or rudder of the Windmill is attached. rlhe base or under surface 27 of the casing acts as a turn table contacting surface enabling the free rotation of the Windmill head upon the turn table in the usual manner.

Having thus described my invention, what l claim as new is:

l. ln power transmission mechanism of the class described, the combination of t casing for containing lubricant, a drive shaft extending thereinto and incliningdownwardly, a drive pinion on said shaft, a driven shaft, gearing operatively connected to the shafts, and a projection on the drive pinion for picking up lubricant from the casing to convey the same to the drive shaft bearings.

2. In power transmission mechanism of the cla-ss described, the combination of a casing for holding lubricant, and including a gear element, a drive shaft projecting thereinto, a drive pinion mounted thereon, a driven shaft extending into said casing, planetary gearing mounted in the casing and operable by the drive pinion aforesaid, said gearing includingn a gear member having an offset hub extending abovethe level of the lubricant and with which the driven shaft is fixed for rotation.

3. ln power transmission mechanism of the class described, the combination of a casing for holding lubricant, a drive shaft projecting thereinto, a drive pinion mounted thereon, a driven shaft extending into said casing, planetary gearing mounted in the casing including a frame consisting of a bottom plate having spacing lugs thereon, an upper plate attached to said lugs, gear elements mounted between said plates, and a relatively large gear secured to the .upper plate and driven by the drive shaft, said driven shaft being secured to said gear elements lfor operation thereby.
